This change removes delay during tuning command for mmc.
Because mmc does not need delay between tuning commands,
and it could cause performance degradation.

This change adds support to field firmware update (ffu) for Samsung emmc
v4.5.
Samsung eMMC 4.5 FFU protocol is similar with eMMC 5.0 FFU without
MODE_OPERATION.
It uses the different EXT_CSD offset.
This patch depends on patch mmc: Support-FFU-for-eMMC-v5.0 committed by Avi
Shchislowski

This change adds support to field firmware update (ffu) for Samsung emmc
v5.0
Some of Samsung eMMC does not show the argument for ffu in ext_csd.
In case of this, eMMC shows 0x0 from ext_csd, Host has to modify the
argument.
And ffu for Samsung eMMC should transfer f/w through not multiple comman
Dear. Jaehoon
I mentioned 3 items.
One is for only Samsung emmc (argument for ffu)
The others are for general emmc
I'll make a separated patch for first item.
But, the others should be applied to this patch.
Thank you.
Best Regards,
Seunguk Shin
